Bluetooth

Getting Bluetooth to work should be trivial assuming you compile the kernel with the following modules enabled:

CONFIG_RFKILL=m
CONFIG_BT_RFCOMM=y
CONFIG_BT_BNEP=y
CONFIG_BT_HIDP=y
CONFIG_BT_HS=y
CONFIG_BT_LE=y

After those are set and you've copied the needed kernel modules over to the rootfs in /lib/modules/ you just need the following firmware files in /lib/firmware/qca/:

crbtfw21.tlv
crnv21.bin

Those can be supplied directly from linux-firmware and they should work fine, but if not you'll need to grab the files from your phone's firmware partitions.
